Yup...I too was looking for that and a similar option of simply removing points. Since we can give points away by mass or donation I'd figure a removal option for Usergroups and individual users would be an option. I know in vBookie you can do so via SQL Query such as:
Code:
UPDATE user SET vbookie_cash='x' WHERE userid='y';
UPDATE user SET vbookie_cash='x' WHERE usergroupid='y';
The "x" is the cash amount while the "y" is the ID. I wonder if there's a way to incorporate a command similar to this as a temporary solution, unless it's already an existing setting in the mod?
